same amount of time, say exercise researchers in Britain. But walks of any length beat sitting at home with your feet up and watching television. They stress. Some researchers in Britain reached these conclusions after putting 56 couch potatoes through an 18 week course of daily walks. They found that longer walks produce the most beneficial changes to the composition of blood fats, but walks of any length improve the fitness of the heart.
In the study, the normally inactive subjects were divided into three roughly equal groups. The "long walker" took a hike of between 20 and 40 minutes every day. "Intermediate walkers" had two rounds of jogging of 10 to 15 minutes, and "short walkers" did three stints of 90 to 110 minutes. The controls sat at home, as usual.
At the start and end of the 18 weeks, the health and fitness of each group were measured and it was found that the long walkers were healthiest, as measured by altered fat profiles in their blood. At the end, each liter of blood from the long walkers contained an average 0.05 grains less apolipoprotein(阿朴脂蛋白) II, a "bad" fat that is linked with heart disease. This was more than twice the drop seen in the intermediate walkers, and five times that in short walkers. In the controls, the level of this fat stayed the same. The drop in apolipoprotein II in the long walker was matched by a rise in the blood level of apolipoprotein I, a "good" fat that is associated with smooth arteries.
